ntrianglesNUMBER (required)

Description

A triangles element stores the entire set of triangles forming a 2-manifold triangulation.

The total number of triangles must be specified by the ntriangles attribute. The individual triangles are numbered 0, 1, 2, etc., and their edge gluings are described by the corresponding child triangle elements. There must be precisely ntriangles child triangle elements in total.

Parents

The following elements contain triangles: packet (2-dimensional triangulation).

Children

The following elements occur in triangles: triangle.

Attributes

ntriangles

The total number of triangles in this set. Note that there must be precisely this many child triangle elements.

Example

The following XML snippet represents a triangulation of the Klein bottle with two triangles. 

<triangles ntriangles="2">
  <triangle> 1 1 1 5 1 0 </triangle>
  <triangle> 0 1 0 5 0 0 </triangle>
</triangles>
